Subject: Re: Cabin heat build up - gear jump
Dear Owen,
two remarks about your point 1: heat leaking into the cabin:
- Arnold Daveys book on page 136 tells you that you are in good company: " comparing the merits of the two models (LG6 and V12), for his extra GBP 300 or so the V12 customer got a reduction in 0-60mph time of about 3 seconds and silky smoothness at all speeds. He also got hot feet and the indefinable cachet of owning the "in" car of the period.."
- I can confirm the engine is producing much heat. I have remade such a cowling over the exhaust manifolds of my midsize V12 de Ville like they had it often originally (A.Daveys book page 134). I think it improved when I bent it down so that some of the upper part of the grille in the bonnet side is not covered by it and allows some of the other hot air under the bonned to get out. This works good enough for me. I think even better might be not to use this but to wrap the exhaust manifold with some of the modern heat shield, but I have not tested it and can not compare. It will keep the under bonnet temperatures low but the exhaust pipes will heat up more under the car..
